I'm trying to get both VLAN Trunking and Q-in-Q working at the same time but to no avail.
I can do either one just fine, the problem is configuring both at the same time in the same CRS. I cannot find any documentations on how to get it done, the ones for them separately do not help much as the configuration conflicts with each other.
Here's my setup:
Also, the double-tagging needs to be completely transparent, that is, I shouldn't have to explicitly configure which VLANs I want to accept inside VLAN 13, it needs to just accept and transport them all. I can easily achieve this in other equipments (including RouterOS software-based) but I'm having a lot of trouble getting it done on a CRS with hardware-based implementation.
The only way I've managed to let it pass any VLAN through it transparently is if I just add them to the same master-port group and don't add any kind of VLAN configuration at all, which defeats the purpose.
